[Haskell-cafe] Re: Efficient parallel regular expressions

[Johannes Waldmann]

using strings (inside a program) to represent structured data
is wrong (*). 

of course you need strings for interfacing the "outside" world, 
but the microsecond they get on the inside,
they should be tokenized and parsed away
into something useful (= an abstract syntax tree).
 
(*) corollary: 
using strings to represent regular expressions is also wrong...
